does any mom knows the best doppler out there I can buy to listen to baby's HR. the wait for ultrasound appointment is killing me.
There is an app for iPhone called shell. It's free and it worked for me.
I got mine from amazon. Wusic, easy to use and found heartbeat right away. comes with two earphones so 2 people can listen at a time, and you can record the heart beat to a computer. I loved it and 100% satisfied
@mandaaleexo thanks
